H. W. TOWNSEND HANDLE AS S EMBLY Filed 001;. 13, 1930 Patented Nov. 10, 1931- HOWARD W. TOWNSEND, OF RICHMOND, INDIANA HANDLE ASSEMBLY Application filed October 18, 1980. Serial No. 488,257.

Broadly stated, my object is to provide a handle assembly which is strong and durable in construction, attractive in appearance, comparatively light in weight, which is practically indestructible, affording a high degree of efficiency in operation, and which can be manufactured, sold, and installed at a comparatively low price.

More specifically stated, my object is to provide a handle intended more especially for lawn mowers or the like, the same being formed entirely of sheet-metal and so constructed that it is adjustable to lawn mowers of various widths, and also having means whereby it may be easily attached in operative position and whereby the several parts may be rigidly secured together under tension, yet permitting it to have the proper amount of resiliency, such as to completely absorb or at least minimize the vibration and twisting caused by the lawn mower when operated over rough and uneven ground, whereby the labor of the operator and the vibrations usually transmitted to ones body and limbs will be practically nil.

Another specific object is to provide a trussed handle by which the body or stem of the handle may be formed of comparatively light sheet metal, yet having means for making it self-supporting and without liability of undue .bending.

Other objects and particular advantages of this invention will be manifest in the course of the following description, and that which is new will be correlated in the appended claims.

The preferred means for carrying out the principles of my invention in a practical and mechanically efficient manner, is shown in the accompanying drawings, in which- Figure 1 is a top plan view of my complete handle assembly.

And Figure 9 1s a perspective view of the lower supporting member of the assembly.

Similar indices designate like parts throughout the several views.

In order that the construction, the arrangement, and the several advantages of my invention may be more fully understood and appreciated, I will now take up a detailed description thereof, in which I will set forth the same as fully and as comprehensively as I may. Referring now to the drawings in detail: The body portion of my handle assembly comprises a channeled member 1 formed of sheet metal providing a central portion and the two side portions which are integral therewith and extending at rightangle thereto, and which are parallel with each other, the cross-section thereof being clearly shown in Figs. 4 and 5.

The lower supporting member, shown alone in Fig. 9, consists of two comparatively short channel members 2a and 2b, which are spaced apart but are in longitudinal alinement with each other, and they are integrally, but indirectly, connected by a yoke, which latter comprises the members 20, 2d and 2e, 35 the latter having an aperture 2; formed through its center. Also a base member 29 connects, on one side, the edges of the members 2c, 2d and 2e, and it has an aperture 2h formed through its center. Said lower supporting member is formed from a single piece of sheet metal cut out fiat and then bent into the shape as shown in Fig. 9. The yoke portion of said lower supporting member is adapted to fit snugly in the channel at the lower end of the member 1, where it is rigidl secured by a rivet 6 which is inserted throug the aperture 27 and a corresponding aperture therefor formed through the member 1.

,

Numerals

3 and 4 denote curved arms,

a lawn mower or other device.

which are also formed channeled in cross section, their horizontal portions being adapted to be nested together, that is they overlap each other at their inner portions; to accomplish which the inner end portion of the arm 3 is slightly smaller, laterally, than the corresponding portion of the arm 4, as shown in Fig. 6. Both of the arms, 3 and 4, are slightly smaller in cross section than are the channeled members 2a and 26, whereby they will fit snugly therein, as shown in Fig. 6. The outer end portions of the

arms

3 and 4 have apertures 8 therethrough as shown in Fig. 3, whereby they may be pivotally mounted to The overlapping portions of said

arms

3 and 4 have apertures 9 formed therethrough, each aperture 9 of one arm being adapted to register with a like aperture 9 of the other arm, whereby said arms may be adjusted laterally, as will hereinafter be more ,fully explained.

The upper supporting member, shown 1 alone in Fig. 8, consists of a flat base member 5, having an end member 5a turned at rightangles thereto, and side members 5b and 50 also turned at right-angles to the member 5 and extending at right-angles from the member 5a.

Opposite to the member 5a a tubular member 5d is formed. An aperture 5e is formed through the base 5, an aperture 5/ is formed through the member 5a, and corresponding apertures 5g extend entirely through the member 5d, in fact forming two apertures, which are very slightly out of alinement with the aperture 5f, for the purpose hereinafter explained.

Said upper supporting member is adapted to fit snugly in the channel of the upper end of the member 1, where it is rigidly secured by a rivet 7, which is inserted through the aperture 56 and a corresponding aperture formed through the member 1.

The central support, shown in Fig. 7, consists of a base member 10, having end members 10a and 10b extending outward at right angles from the member 10 and formed integral therewith. Apertures 100 and 10d are formed through the respective members 10a and 10b. Said central support is adapted to fit snugly in the channel of the member 1, as shown in Fig. 2.

Numeral 12 denotes a stay rod, which has a head 12a formed on its upper end, and its lower end portion is threaded to receive the nut 13 thereon.

Numeral 14 denotes the handle-bar which fits tightly in the tubular member 5d, where it is centrally located with relation thereto, with an aperture (not shown) formed entirely therethrough, which aperture registers with the aperture 5g.

Numeral 15 denote grip cushions, which are formed of rubber or other suitable material. Said cushions are simply forced. over the end portions of the bar 14, as in Fig. 2',

or they may be entirely omitted, as in Fig. 1.

In assembling my construction the lower support member is secured to the member 1 by the rivet 6; likewise the upper support is secured to the member 1 by the rivet 7. The central support is inserted in the channel of the member 1, but is not necessarily secured to the member 1.

The next operation is to insert the handle bar 14 into the member 56!. Next the rod 12 is inserted through aperture 5g, and the apertures in the handle bar, and continuing it on through the aperture 5f, forcing it downward until the threaded end thereof is near'th-e central support, at which time it will be inclined to be some distance out of alinement with the apertures 10c and 10d thereby necessitating that it be sprung toward the member 1 in order to enter it in said apertures, through which it is then forced and from which it is then forced downward and then entered in the aperture 2 The inner end portions of the

arms

3 and 4 are then overlapped with relation to each other, bringing an aperture 9 of each into register with each other, and with the aperture 2;. The end of the rod 12 is then forced into said registering apertures, but before being projected therefrom the nut 13 is placed in position and the threaded end of the rod is then turned, by turning the head 12a, causing it to screw into said nut, the nut being locked from turning by reason of its location in the channel of one of the arms.

Said rod is to be turned by means of a wrench applied to the head 12a, and by this means it is tightened until all of said parts are securely clamped together in the relative positions shown in Fig. 1, thereby completing the assembly.

It should be observed, by reason of the rod 12 being first inserted through the handlebar and the upper supporting member, that when it is brought down to its final position that it will cause the handle-bar to be more secure and without danger of its becoming loose. Also it should be observed that as the apertures 10c and 10d are farther from the central portion of the member 1, than are the apertures 2; and 5f, that the rod 12 forms a truss, under tension, such as to prevent the handle from bending under unusual strain. Also the entire assembly is such as to accomplish the objects previously enumerated herein. \1

I desire that it be understood that various changes may be made in the several details herein set forth, in order to accommodate my invention to various purposes, without sacrificing any of the advantages thereof which are new and useful which involve invention.
